The Nurse Researcher Is Conducting a Research Study on the Association

The nurse researcher is conducting a research study on the association between aging male populations and the development of prostate cancer. The nurse uses a sample of 50 males older than 80 years of age. The quantitative research finds that many of the participants developed cancer after age 80 years. Which is the flaw in this research if the nurse reports all males over 80 years of age will most likely develop prostate cancer?

A) The problem statement does not provide enough information.
B) Sample size is too small to make a generalization.
C) The research is only valuable to those working with aging males.
D) The research design is most likely inappropriate for the type of study.
